Opinion on a Libertarian united world?

So what makes us libertarian? We don’t like strong goverments or goverments at all. And we most likely like capitalism.

But there is something I see as problematic. We don’t like each other so much that we are still divided.

I’m just getting to the point now. I personally belive that a world where we speak one language, borders don’t exist and if possible use one currency globally, with regional cultures being a thing and where we are united by a VERY LIMITED world goverment in a capitalist economic system, is beneficial.

You may call me a madman and the conservatives are probably angry as fuck, but let me give you some reasoning, why I belive this.

First, I belive in the limited goverment and capitalism, because I can see the opposite of it in first hand. I’m from Hungary, a post-socialist nation. We have experienced fascism and communism. And they sucked. A goverment with basically unlimited power did no good for is. And socialism just simply sucks. It’s not sustaining. That is why I call myself a libertarian, because I hate strong goverments and leftist economies.

And why do I belive in a united world goverment? Just look at history. We kept murdering each other over any differences. Someone belives in a different god, a group of people looking different from the other, they speak different language. Just think about what humanity could be if we just gave up our stubborn need for national soveregnity, let go of the past and finally unite. We could have colonised Mars by now, or even other solar systems, if we were united centuries ago.

I know I’m being idealistic, but I’m allowed to dream. And yes, people like Klaus Schwab and maniacs like him also want a global power, but with their rule. I also want a global power but without any of them, where the economy thrives and companies do their jobs.

And I’m here to ask you guys for opinion. Am I dumb? Is this a wrong idea, and if yes, why? Or this could be a good idea with some twists? I accept if I’m proven wrong.
